Abstract
A surgical tool for cutting, shearing or clamping has a body formed of a single length of flexible steel and a collet mounted perpendicularly between the leaves of the body and affixed between the leaves near their rearward ends. The leaves are normally bowed outward, so that squeezing them together lengthens the body, thus producing relative displacement between the forward ends of the body and collet, respectively. The bifurcated forward end of the collet, which extends through an aperture in a bridge joining the leaves, terminates at a pair of jaws having inwardly working surfaces and outwardly facing cam surfaces. The cams are engaged by the sides of the aperture, which drive the jaws together when the leaves are squeezed toward one another.
